森林立地类型的划分,自八十年代以来,主要是应用数量化回归和逐步回归的方法。这两种方法都是采用多元分析的理论,定量评定立地质量,对有林地和无林地均适用,是一种较先进的方法。但严格说来,这两种方法只能较好地评价立地质量,还不能对立地类型进行合理的划分。我们认为,科学合理的立地类型划分,必须以数量指标为尺度,以最能准确地反映各不同立地类型 Since the 1980s, the classification of forest site types has mainly been the application of quantitative regression and stepwise regression. Both of these methods are based on the theory of multivariate analysis. Quantitative assessment of site quality is applicable to both forested and non-forested areas and is a more advanced method. Strictly speaking, however, these two methods can only evaluate the quality of the site well, and can not reasonably divide the site type. In our opinion, the division of the scientific and rational site types must be based on quantitative indicators to best reflect the different site types
